Nouns—People, Places, Things
6.01 | Proper and common nouns.
A noun is a word that names something. It can be a person’s name, a place, a thing, or an
abstract quality such as justice, truth, or happiness. A proper noun names a particular or special
place, person (or people), or thing. A proper noun is always capitalized (America, Joseph, Italy,
Microsoft, etc.) A common noun is a general or class noun that names an object or abstract
quality, and it is written in lower-case.
6.02 | Forming plural nouns.
A singular noun refers to one of something, a plural noun refers to more than one. Plurals of
singular nouns are formed based on specific rules, with a handful of exceptions.
1. For most nouns, add s to the singular: car+s = cars; house+s = houses; war+s = wars.
2. For most nouns ending in s, ch, sh, or x, add es to the singular: box+es = boxes; dish+es =
dishes; class+es = classes; watch+es = watches.
3. For nouns ending in y preceded by a vowel (a, e, i, o, u), add s to the singular: boy+s = boys;
pray+s = prays; valley+s = valleys. Two exceptions: soliloquy = soliloquies, and colloquy =
colloquies.
4. For nouns ending in y preceded by a consonant (any letter other than a vowel), change the y
to i and add es: army = armies; pony = ponies; sky = skies.
5. For most nouns ending in f or fe, add s to the singular: cliff+s = cliffs; knockoff+s =
knockoffs; safe+s = safes.
However, a few nouns change f or fe to v and add es: wife = wives; self = selves; half = halves.
Others include: calf, elf, half, knife, leaf, life, loaf, sheaf, shelf, thief, wharf, wife, wolf. (Wharf
has also a plural, wharfs.)
6. For most nouns ending in o, add s to the singular: cameo+s = cameos. But for some nouns
ending in o and preceded by a consonant, add es: volcano+es = volcanoes. Other nouns in this
class are: buffalo, cargo, calico, echo, embargo, flamingo, hero, motto, mulatto, potato, tomato,
tornado, torpedo, veto.
